element switch

The switch to turn on the element is not letting power though. I assume the ?fuseible link" or whatever that mesh type strip onthe back of the points arm is not repairable? that is where the power is stopping. it gets to the arm on the back but not to the terminal. How do I choose which switch to replace it with? I replaced the element thinking that was the problem. but it is the switch. the element is a 2200W. there is a 1400 and 2400W available in parts.
